About the Video Trimmer

Trim the exact moments you need. Type a start time and an end time and ToolNest cuts the segment locally with FFmpeg in your browser. Nothing is uploaded, so it is safe for private footage.

The output is re-encoded to MP4 (H.264 + AAC), the most compatible format there is, so your trimmed clip plays everywhere — perfect for social posts, presentations and messaging apps.

Frequently asked questions

How accurate is the cut?

Frame-accurate. The segment is re-encoded locally, so the clip starts and ends exactly where you asked.

Can I trim WebM or MOV files?

Yes — any input format works. The trimmed clip is always saved as MP4 for maximum compatibility.

Does the trimming upload my video?

No. Cutting happens inside your browser. The file never leaves your device.
